Optional Standard Deduction for Individual Taxpayers
Updated June 13, 2026

Definition
The Optional Standard Deduction (OSD) is a simplified deduction under NIRC §34(L) that lets individuals in business or professional practice deduct 40% of their gross sales or gross receipts instead of itemizing actual business expenses. Corporations may also elect it, at 40% of gross income. There is no peso cap.
The Optional Standard Deduction has been part of the National Internal Revenue Code since 1997. RA 9504 raised it to 40% in 2008, and the TRAIN Law (RA 10963) kept it. Instead of keeping detailed records of business expenses and itemizing each one, taxpayers can elect the OSD and deduct a flat 40% of their gross sales or receipts. This system is particularly beneficial for professionals, self-employed individuals, and mixed income earners who may have difficulty tracking all allowable business expenses. The OSD covers what would typically be claimed as business expenses such as office supplies, transportation, communication costs, professional fees, and other ordinary and necessary business expenses. It does not apply to compensation income. The election is made on the first quarterly income tax return of the year and is irrevocable for that year. Taxpayers report it on BIR Form 1701 or 1701A.
Detailed explanation
What is the Optional Standard Deduction?
The Optional Standard Deduction (OSD) under NIRC §34(L) lets individuals engaged in business or the practice of a profession deduct 40% of their gross sales or gross receipts instead of itemizing their actual expenses. Corporations may also elect it, at 40% of gross income. It has been in the Tax Code since 1997, was raised to 40% by RA 9504 in 2008, and was kept by the TRAIN Law (RA 10963).
How the OSD Works
A self-employed professional with ₱1,000,000 in gross receipts deducts ₱400,000 and is taxed on ₱600,000. There is no peso cap: a professional with ₱5,000,000 in receipts deducts ₱2,000,000. For individuals selling goods, the 40% is computed on gross sales, and cost of goods sold is not deducted separately.
Eligibility and Scope
The OSD is available for income from business or professional practice. It does not apply to compensation income, which has no deduction at all. The taxpayer chooses between the OSD and itemized deductions on the first quarterly return of the year, and the choice is irrevocable for that year. The taxpayer may switch methods in a later year.
Comparison with Itemized Deductions and the 8% Option
If actual deductible expenses (rent, utilities, supplies, professional fees, depreciation) are higher than 40% of gross sales or receipts, itemizing gives a lower tax. If they are lower, the OSD is simpler and cheaper. Taxpayers with gross sales or receipts of ₱3,000,000 or less who are not VAT-registered should also compare the 8% rate, which replaces both graduated rates and percentage tax.
Record-Keeping and Compliance
While the OSD reduces the burden of itemizing, taxpayers must still keep records proving their gross sales or receipts (invoices, official receipts, bank statements). The BIR may audit to verify income figures. Choosing the OSD removes the need to substantiate expenses, not income.
Why it matters
The Optional Standard Deduction simplifies tax filing for self-employed Filipinos and professionals by removing the need to substantiate every business expense. It lowers compliance costs for small and medium earners, and every taxpayer can compare it with itemized deductions and the 8% option to find the lowest tax. Understanding when to use OSD can save thousands of pesos in record-keeping or overpaid taxes.
How it works
Calculate 40% of Gross Sales or Receipts
Determine your gross sales (for sellers of goods) or gross receipts (for services and professions) for the taxable year. Multiply by 40% to find your deduction. For individuals, cost of goods sold is not deducted first; the 40% replaces it (NIRC §34(L)).
There Is No Peso Cap
The deduction is always 40% of gross sales or receipts, however high they are. A professional with ₱5,000,000 in receipts deducts ₱2,000,000 and one with ₱10,000,000 deducts ₱4,000,000 (NIRC §34(L), as amended by RA 9504).
Compare with Itemized Deductions and the 8% Option
Calculate your actual business expenses (rent, utilities, supplies, salaries, depreciation). If they are higher than 40% of gross sales or receipts, itemizing gives lower taxable income. If your gross sales or receipts are ₱3,000,000 or less and you are not VAT-registered, also compare the 8% rate, which replaces both graduated rates and percentage tax.
Elect It on Your First Quarterly Return
Signify your choice on the first quarterly return of the year (BIR Form 1701Q). The election is irrevocable for that year. Report it again on your annual return, BIR Form 1701 or 1701A, filed by April 15 of the following year (NIRC §51).
Examples
Self-employed consultant earning ₱600,000 annually
Maria Santos, a management consultant, has ₱600,000 in gross receipts. Her 40% OSD is ₱240,000, more than her ₱85,000 of actual expenses. Taxable income is ₱360,000 and income tax is 15% × ₱110,000 = ₱16,500, plus 3% percentage tax of ₱18,000, or ₱34,500 in total. The 8% option would cost ₱28,000, ₱6,500 less, so she should compare both before filing her first quarterly return (NIRC §34(L)).
Small business owner with ₱1,500,000 gross sales
Juan dela Cruz runs a retail shop with ₱1,500,000 in annual gross sales. His 40% OSD is ₱600,000, against ₱510,000 of documented expenses, so he elects OSD. Taxable income is ₱900,000 and income tax is ₱102,500 + 25% × ₱100,000 = ₱127,500 (NIRC §34(L)).
High-income professional earning ₱5,000,000 annually
Dr. Anna Reyes, a physician, has ₱5,000,000 in gross receipts. Her 40% OSD is ₱2,000,000 (no cap applies), more than her ₱1,500,000 of actual expenses. Taxable income is ₱3,000,000 and income tax is ₱402,500 + 30% × ₱1,000,000 = ₱702,500. With receipts above ₱3,000,000 she cannot use the 8% option and must register for VAT (NIRC §34(L), §109(CC), §236).
Freelancer with ₱800,000 gross receipts and high expenses
Pedro Santos, a freelance software developer, earns ₱800,000 a year. His 40% OSD is ₱320,000, but his documented expenses total ₱344,000, so he itemizes. Taxable income is ₱456,000 and income tax is ₱22,500 + 20% × ₱56,000 = ₱33,700 (NIRC §34(A)).
Common misconceptions
- Myth: The Optional Standard Deduction means I pay no tax on 40% of my income.
- Fact: The OSD is a deduction, not an exemption. You deduct 40% from gross sales or receipts to calculate taxable income, then apply the graduated rates to the rest (NIRC §34(L)).
- Myth: Once I choose the Optional Standard Deduction, I must use it every year.
- Fact: You may switch between OSD and itemized deductions from year to year. The election is made on the first quarterly return and binds you only for that year (NIRC §34(L)).
- Myth: The OSD is capped at ₱2,000,000.
- Fact: There is no cap. A professional with ₱10,000,000 in gross receipts deducts ₱4,000,000 under the OSD (NIRC §34(L), as amended by RA 9504).
- Myth: I do not need to keep receipts if I use the Optional Standard Deduction.
- Fact: You must still keep records proving your gross sales or receipts (invoices, bank statements, sales records). The BIR may audit to verify income. The OSD removes the need to substantiate expenses, not income (NIRC §34(L)).
Questions people ask
Can I use the Optional Standard Deduction if I am an employee?
No. The OSD is available only for income from business or the practice of a profession. Compensation income has no deduction at all; employees reduce taxable income only through the exclusion of mandatory contributions, 13th month pay and other benefits up to ₱90,000, and de minimis benefits. Mixed-income earners may use the OSD on their business income only (NIRC §34, §34(L)).
What happens if my actual business expenses exceed the Optional Standard Deduction?
You may elect itemized deductions instead. Calculate your actual deductible expenses (rent, utilities, supplies, salaries, depreciation, etc.) and compare them with 40% of your gross sales or receipts. If itemized deductions are higher, claim them on your return. You choose the method that results in the lower taxable income (NIRC §34(A), §34(L)).
Is there a maximum OSD amount?
No. The OSD is always 40% of gross sales or receipts for individuals (40% of gross income for corporations), with no peso ceiling (NIRC §34(L), as amended by RA 9504).
Can I claim both the Optional Standard Deduction and itemized deductions in the same year?
No. You must elect one method per taxable year, on your first quarterly return, and the choice is irrevocable for that year. You may switch methods in a later year (NIRC §34(L)).
How do I report the Optional Standard Deduction on my tax return?
Signify the election on your first quarterly return (BIR Form 1701Q), then report it on your annual return, BIR Form 1701 or 1701A, filed by April 15 of the following year. Enter your gross sales or receipts and the 40% OSD amount in the deductions section (NIRC §51).
What if the BIR audits my income and finds it was higher than reported?
If the BIR finds unreported income during an audit, your gross sales or receipts are adjusted upward, which also increases your OSD (40% of the revised figure). Your taxable income and tax are recalculated, and you may face a 25% surcharge plus 12% interest a year on the unpaid tax (NIRC §248, §249).
Can I use the Optional Standard Deduction if I have multiple sources of income?
The OSD applies to your total gross sales or receipts from business and professional practice. Employment income is computed separately and cannot use the OSD. Combine your business and professional receipts to calculate the OSD, then add your taxable compensation (NIRC §34(L)).
In practice
- Self-employed professionals and business owners use the OSD to avoid tracking every expense receipt, which cuts compliance time for small and mid-sized practices.
- Taxpayers with highly variable monthly expenses (consultants, freelancers) often find OSD more convenient than itemizing, as it provides a predictable deduction regardless of actual spending patterns.
- Taxpayers whose real expenses run above 40% of gross sales or receipts, such as resellers with low margins, usually itemize instead.
- The OSD is elected on the first quarterly return (BIR Form 1701Q) and applies for the whole year; a taxpayer who does not signify it is treated as using itemized deductions.
- Switching from itemized to OSD (or vice versa) in subsequent years requires no special approval; simply report the chosen method on the new year's return.
